Abstract
Vapor lock characteristics of a group of late model cars were evaluated, using a new part throttle procedure for simulating high temperature operation. Ten cars using three reference fuel series having diverse front end volatility characteristics showed an average difference of 1.3 lb, RVP with the low and high volatility fuels. Comparisons of wide-open throttle and part throttle requirements using intermediate volatility fuels showed an average decrease of 1.7 lb, RVP at wide-open throttle. Temperature for a vapor lock ratio of 15:1 was found to be superior to other expressions in predicting vapor locking performance of gasolines.
